Upload users

Firstly, note that it is usually not necessary to import users in bulk
- to keep your own maintenance work down you should first explore forms
of authentication that do not require manual maintenance, such as
connecting to existing external databases or letting the users create
their own accounts. See the Authentication section in the admin menus.

If you are sure you want to import multiple user accounts from a text file, then you need to format your text file as follows:

Each line of the file contains one record

Each record is a series of data separated by commas

The first record of the file is special, and contains a list of fieldnames. This defines the format of the rest of the file.

Required fieldnames: these fields must be included in the first record, and defined for each user

username, password, firstname, lastname, email

Default fieldnames: these are optional - if they are not included then the values are taken from the primary admin

institution, department, city, country, lang, auth, timezone

Optional fieldnames: all
of these are completely optional. The course names are the "shortnames"
of the courses - if present then the user will be enrolled as students
in those courses. Group names must be associated to the corresponding
courses, i.e. group1 to course1, etc.

Commas within the data should be encoded as &#44 - the script will automatically decode these back to commas.

For Boolean fields, use 0 for false and 1 for true.

Types
are used to tell Moodle whether the user is a student or a teacher if a
corresponding course exists (e.g. type2 corresponds to course2). 1 =
Student, 2 = Editing Teacher, and 3 = Non-editing Teacher. If type is
left blank, or if no course is specified, the user is default to
student.

For courses use the short name; for groups use group name; for roles use id.

Note: If a user is already registered in the Moodle user database, this script will return the
userid number (database index) for that user, and will enrol the user as a student in any of the
specified courses WITHOUT updating the other specified data.

Updating existing accounts

By default Moodle assumes that you will be creating new user
accounts, and skips records where the username matches an existing
account. However, if you set "Update existing accounts" to Yes, the existing user account will be updated.

When updating existing accounts you can change usernames as well. Set "Allow renames" to Yes and include in your file a field called oldusername.

Warning: any errors updating existing accounts can affect your users badly. Be careful when using the options to update.
